I am looking for a usb gps to buy as my bluetooth is not going me anywhere ( it needs pairing and confirmation code every time ). So i wanted to ask if there are out there gps usb modules with the option of an external antenna. if not are you happy with these globalsat devices ? Do they have tmc too ?

That was the first thing . The second one is that i am running out of free usbs . WHat do you suggest . A usb hub will do the work . Are there any other solutions .

OK all the boards I have here at the moment, I have removed the serial port from the board. I can solder up one tonight but you can add 5v to the board if it needs it via the USB A socket pinout as they only populate the mini-usb port. it only draws 50ma SNO
